Blanket.

Recommended Posts

I've seen a couple threads here about chainmail blankets for assorted purposes, and there are the occasional hits across the web too.

I'm not trying to cure RLS or calm an ADHD child, I just grew up in the great white north and work has moved me to the desert. I missed the weight of blankets and wanted one that would actively cool instead of insulate. Metal was the obvious choice for high thermal conductivity and surface area, and maille was a natural mode of construction. This place was my next stop.

I'm sure most of you folks have been excited about a box like this one that delivered three months ago:

This was my very first foray into mail construction, and it seemed pretty daunting to start off with a 20lb, spool but my girlfriend deployed so I have time on my hands. I wound all 20lbs into coils in a weekend spent on my front porch. I lost a little blood to springback despite knowing it was there, lurking. Took me a little bit to refine my technique, I guess.

 

 

First milestone: big enough to sleep under. Mid-June, I had made an aluminum bath towel.

Tonight's milestone: it drapes off the edges of the mattress!

I'm sure lots of you have worn this stuff in cooler weather and know just how effectively it serves as a radiator, so you'll understand how my AC set to 78F means I wake up shivering some nights. It may take a couple years to break even on the cooling costs since I only cool my bedroom, but this is infinitely more comfortable.

 

Now for the technical stuff where you're the experts: as I move out to the edges of the project, should I be concerned with stretching? This is 14g bright Al with 5/8"+ID. I need enough drape to prevent the edges from rolling onto the bed and bunching up around bodies, because the next thing that happens is (thanks to the 4-in-1 bias) a lengthwise expansion where the sheet drapes off the foot of the bed, and suddenly my blanket is made entirely of wheels in a race for the floor.

 

My friend's sewing a dedicated flat sheet with some ties to attach the rings, but that won't be rigid enough to resist 20lbs of gravity if the thing decides it's go time, so the side tension is important.

 

If total weight/stretching is a risk, should I reduce the weave density off the sides, maybe by leaving out one in eight of the 4e1, or even further and just putting strands/tassels?

 

If i want to increase the weight of the sheet at the neck/shoulder edge to help resist rolling down the body's taper, what's a good way to do so? Switch to a few rows of steel, weave the aluminum in a thicker pattern? Both?

Well the simplest way would be to use 8-2 (kings maille.) where you want more weight. Meaning you simply double the rings. Might not be elegant but often the simplest answer is the best. This will lessen the "stretch" of the weave though do keep that in mind.

Personally I would avoid mixing metals on something that is going to see a fair deal of movement. While I have not tested it my gut tells me the steel would wear on the aluminum over time.

cool, i didn't think of the increased wear. the 8-2 was the first candidate, because it would sort of interface 1:1 with the existing rings. will the steeper ring angles make the 8-2 weave column significantly shorter?

  Yes that's what I meant by lessening the "stretch". As I am sure you noticed while working with it that E4-1 sort of stretches in one direction. Now if you had made the stretching direction top to bottom it would not have much of an effect putting 8-2 at the top. But looking closely at the pic it seems that you went left to right. This means 8-2 would cause it to pull in a bit. How much I really couldn't say. 

 

  Another option is E6-1. Its not any big deal to attach it to 4-1 and I believe would have less of a shortening effect? (maybe someone wiser then I can confirm.) But it would not add as much extra weight as 8-2 would.

Ahh, OK, I follow now.

 

Yes, I do have it oriented left to right. In testing, I found that if I went top to bottom, when the mesh drapes off the sides, it stretches across the bed and suddenly my blanket is 2x8' instead of 6x6'.

 

Do you think edges or distributed ribs and spars of 8-2 help maintain square?

that's excellent, Konstanin. I imagine that adding something so dense as a J12-2 would be like attaching flexible beams. If I wanted to incorporate that, how would I attach it to the e4-1? Just lay it down in the direction of resisted expansion while the blanket is open-hang and loop in a ring every few inches?

I am litterally like 2 minutes away from calling my wife over to see this and see if I can put one on our bed. Keep up the good work, I hope the advice others have given helps you! (Sorry I can't offer more help.)

Latest breakthrough: using http://smile.amazon.com/The-ORIGINAL-Bed-Band-Adjustable/dp/B004I3VDWY/ref=sr_1_1?ie=UTF8&qid=1408602460&sr=8-1to keep the quilt at open hang, max width at the foot means i don't wake up to the sensation of the blanket being pulled off me anymore. I had tried stringers of paracord to limit the available length in lieu of the suggested persian 3 in 1 but the retaining bands work a treat

How is the finished blanket treating you Myrt? Are you using it on top of you as a blanket or as a sheet? 

How many hours did you spend making it? Would you be interested in making another? If so, how much would you charge?

 

thanx

Howdy! The blanket has been amazing through four pretty serious summers out here in the desert. I use it over a cotton sheet usually, it's too cold for direct contact except during the hottest of monsoon weather. I have awoken shivering and cold with an indoor air temperature of 78F, a moderate fan blowing, and a sheet between us.

I worked on it somewhat casually through all of Breaking Bad and Dexter (pretty long time). This was my first chainmail project, so my assembly rate starting out was not so quick. Having met my needs and as I work full time, I don't plan to do another, although I saved some coils in case I get a bigger bed.

I still have the mandrels too - although I'd say that TRL's recommendation to buy two is probably meant for much less substantial models than the 5/8" rods.

I suppose that'd be the case for mandrels, as far as variety of link diameters goes.

I don't particularly need any such appliance, living next to the ocean as I do, kind of the anti-desert temps-wise, but its cooling effects I note with interest and will keep in mind if it's ever called upon.  I can cite Myrt as having succeeded with this.
